So, the question is: Why? Here are a few ideas that may help get started answering that question.
Managing Project Management
The key part of each project comes even before the project begins. This is in the estimation phase of the project. Even if you have executed a similar project in the recent past, it is best not to conclude the effort involved in executing the project will be the same.
The big difference will be that the users for this project are different. That means different expectations. The estimation of each project has to take into account all the unique variables that are involved in that particular project.
Here are few other things that might change and may affect your project comparison estimates:
Focus on Design
Every hour you spend on design will yield great dividends later. The problem though is that the output of design usually is a set of documents. If the right expectations are set, however, this may be just fine. Otherwise, you may need to explain why there is no measurable progress on the project.
We all know how difficult it is to get the "perfect team on a project. When we assemble the resources for the project, we know that we are using the best of what is available to us at that time.
What is often forgotten forget is that once the resources are in place, we expect them to be the perfect fit for the project. It is important for the project leader to know the strengths and weaknesses of the team members and factor that into the work-design for the project.
When is a good time to get closer involvement with the users? No, the right answer is not throughout the project. That may harm rather than help. So, what is the right answer? Balance.
Involving users more than required will put a drag on the project and involving them less than required will create a lack of buy-in. Your first objective will be identify the influencers among the users and try to get their buy-in. Once the influencers buy-in, they will influence the others.
Very rarely do you come across projects that are standalone in nature. Projects typically plug-in to an enterprise ecosystem that is already in place.
This important factor should be remembered throughout the project. Your project may be impacted by changes in the other parts of the enterprise ecosystem that touch your project or your project may impact other projects (and probably will).
It is important to know where your project fits in the ecosystem and understand all the dependencies (both ways) for the project.
Client and Industry Dynamics
This is usually the piece that gets missed. For example, suppose you are executing a year-long project for a client (or for your own company) that is in a fast changing industry. Even if the users guarantee you the requirements are frozen, you rest assured that they are going to change sometime during the project.
That has to happen because the business will not be the same a year from now. So, what can you do? For one, you can start looking at items above and beyond the project deliverables; understand the companys business at a deeper level and look at the industry dynamics more carefully. Then, factor that information into your estimation methodology.
Second, you could break the project into smaller pieces and create two or three sub projects of six months or less in duration. Once you complete the first project, you can scope the subsequent ones separately.
Third, collect some history and metrics on past projects in the same department and use that information in your estimation process.
We all know that what I touched on here is just the tip of the ice berg and each one of this topics would probably make for a good book, but it should provide you some food for thought.
